We said earlier that this simulation would model the effect of selection on a population of prey organisms. What was the selective force in this experiment? Was selection effective in bringing about change in the make-up of the prey population? What factors do you think determined how effective selection was?

the oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. this blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. from the left ventricle, the blood passes through the aortic valve to the aorta.

deoxygenated blood leaves through the right ventricle through the pulmonary artery. from the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.

if your own plato the answer is b. the fern transitioned from sporophyte generation to gametophyte generation.
